I've completed the mario program and it works fine! When I re-checked the pset specification page, I found that I should accept
non-negative integer no greater than 23.
So I edited my code to accept
0, which is a non-negative integer. And I'm getting this error when checking my program with check50
:( handles a height of 0 **correctly** \ expected an exit code of 0, not output of "##\n"
Is the check function wrong? Or is my program supposed to be buggy and giving an error when inputting
